</div><h4>Requirements:</h4>
<p>This function must not be called outside of a catch block.</p>
<h4>Returns:</h4>
<p>If the current exception object can be converted to boost::<span class="RenoLink"><a href="exception.html">exception</a></span> or std::exception, this function returns the same string value returned by <span class="RenoLink"><a href="diagnostic_information.html">diagnostic_information</a></span> for the current exception object. Otherwise, an unspecified non-empty string is returned.</p>
<p>Typical use is to call <span class="RenoLink">current_exception_diagnostic_information</span> from a top-level function to output diagnostic information about unhandled exceptions:</p>
<pre>int
main()
    {
    try
        {
        run_program();
        }
    catch(
    error &amp; e )
        {
        //handle error
        }
    catch(
    ...)
        {
        std::cerr &lt;&lt; "Unhandled exception!" &lt;&lt; std::endl &lt;&lt;
            boost::<span class="RenoLink">current_exception_diagnostic_information</span>();
        }
    }</pre>
